HTS Chapter 84 covers industrial machinery – boilers, engines, pumps, compressors, machine tools, and machinery for specific industries. Classification depends heavily on function and end-use. Boundary cases between Chapter 84 and Chapter 85 (electrical equipment) and Chapter 90 (precision instruments) are common.
This guide covers HTS Chapter 84 Machinery Classification. HTS classification is the legal foundation of import duty calculation.
For SMB importers, the practical implementation depends on volume, sector, and operational structure.
Chapter 84 structure
Headings 84.01-84.87. Organized by function: power generation, fluid handling, materials handling, manufacturing processes, specific industries.
Common boundary cases
Machinery with electrical components: Chapter 84 vs 85. Machinery with precision measurement: 84 vs 90. Machinery for specific industries: general 84 heading vs industry-specific.
Function-based classification
Primary function of the machinery determines classification. End-use intent supports the function determination.
Section 232 derivative scope
Some Chapter 84 machinery falls within Section 232 steel/aluminum derivative scope. Component-level analysis identifies coverage.
Frequently asked questions
When does this apply?
For SMB importers with active duty exposure or those evaluating mitigation options.
What documentation is required?
Standard CBP forms plus topic-specific supporting records. We review documentation as part of typical engagements.
What is the timeline?
Simple cases 2-4 weeks; complex setups 8-16 weeks.
What does this cost?
Project work: $5,000-$25,000 depending on complexity. Ongoing retainer for active operations.
